Abstract
Device for measuring thermodynamic characteristics of a fluid sample, comprising in combination: a high-pressure cell (6) equipped with a motorized piston, a drying oven surrounding the cell and intended to vary the cell temperature, motorization means arranged outside the drying oven, means for stirring the fluid placed within the cell, a frame supporting said oven and means (1) for tilting said frame so as to tip the cell up. The cell comprises:—a specific head for measurements on condensate gas wherein a chamber (42) of elongate shape along the axis of the cell is intended to collect the liquids, and—means (44) for visualizing the position of the liquid/gas interface.
